FIELD OF THE INVENTION

The present invention relates to imaging systems for vehicles and, more particularly, to rear vision systems or back up aids for vehicles.

BACKGROUND OF THE INVENTION

It is known to provide a rearward facing camera or imaging sensor or device at a rear of a vehicle and with a generally rearward and downward field of view to capture images of the area immediately rearward of the vehicle for a rear vision system or back up aid system or the like. Examples of such rear vision devices and systems are described in U.S. Pat. Nos. 7,005,974; 6,989,736; 6,757,109; 6,717,610; 6,396,397; 6,201,642; 6,353,392; 6,313,454; 5,550,677; 5,670,935; 5,796,094; 5,877,897; 6,097,023 and 6,498,620, and International Publication No. WO 2004/047421, published Jun. 3, 2004, which are all hereby incorporated herein by reference in their entireties. Such devices and systems perform adequately for their particular applications.

It has been suggested that such imaging devices be located at the license plate well or under the sill or overhang portion at the license plate well or recess, such as, for example, as is common on tail gates or lift gates of SUVs, minivans or the like. However, it is desirable that such rearward and substantially downward facing imaging devices be generally centrally located at the rear of the vehicle, and many vehicles have a trunk or lift gate release handle at the central region of the sill or overhang portion, such that an imaging device cannot be centrally located at the recess or well of the rear license plate. It has been suggested to incorporate an imaging device in an extendable/retractable device so that the imaging device may extend or be moved outward or rearward when it is desired to capture images so as to provide an enhanced rearward and downward field of view for the imaging device when so extended, and may retract within or partially within the rear portion of the vehicle when not in use. Such devices are typically costly and complicated devices and have not yet achieved widespread commercialization.

Therefore, there is a need in the art for an improved rear imaging system that overcomes the shortcomings of the prior art.

SUMMARY OF THE INVENTION

The present invention provides an imaging system with an imaging device at a rear portion of the vehicle and directed to have a generally rearward and downward field of view. The imaging device is located at a decal or indicia of the vehicle, such as at a rear tail gate or deck lid handle or the like, and may be located rearward of the rear surface of the tail gate or deck lid so as to provide a generally rearward and downward field of view. The imaging device or camera is thus camouflaged or rendered covert or covertly located by utilizing the exterior trim elements of the vehicle that are readily accessible and that may be modified or extended to accommodate the imaging device or camera.

According to an aspect of the present invention, a rear vision system for a vehicle includes an image processing device, a display device and an imaging device or sensor or camera. The imaging device is located at a rear portion of the vehicle and has a generally rearward and substantially downward field of view for capturing images of the area substantially immediately rearward of the vehicle. The imaging device is positioned at least partially within an extender element that extends from a rear surface of the vehicle. A vehicle emblem or decal or exterior trim component is attached to or included as part of the outer or rearward end or surface of the extender element so that the extender element is not readily noticeable or discernible by a person viewing the rear of the vehicle.

The extender element and imaging device may be installed to the rear of the vehicle during manufacture of the vehicle. Optionally, the decal or emblem or exterior trim component of an existing vehicle may be removed from the rear portion of the vehicle, and the extender element and imaging device may be attached to the rear portion as an aftermarket device. The decal or emblem may be reattached to or replaced at the outer or rearward end or surface of the extender element, or a new decal or emblem may be included as part of the extender element.

According to another aspect of the present invention, a vehicle vision system includes a vehicle having a body surface and a vehicle element generally at the body surface. The vehicle element defines at least one of a styling feature and a functional feature of the vehicle and has a normal distance dimension relative to the body surface of the vehicle. An imaging device has an exterior field of view generally exterior of the vehicle, and captures images of a region external of the vehicle. An extender element at the body surface extends outwardly therefrom, with the vehicle element being disposed at an outer surface of the extender element. The extender element extends the normal distance dimension of the vehicle element for accommodating the imaging device. The imaging device is disposed at least partially within the extender element, whereby the presence of the imaging device in the extender element is at least partially masked or camouflaged by the extender element and the vehicle element. The vehicle vision system includes a display device for displaying video images captured by the imaging device.

Optionally, the body surface is at a rear portion of the vehicle, and the imaging device may have a generally rearward and downward field of view, whereby the imaging device captures images of the area substantially immediately rearward of the vehicle. Optionally, the display device may display images of the rearward and downward field of view in response to the vehicle being shifted into a reverse gear.

Optionally, the extender element may be fixedly attached at body surface or the rear portion of the vehicle. Optionally, and desirably, the extender element may have a surface finish that substantially matches a surface finish of the body surface of the vehicle. Optionally, the vehicle element may be adhesively attached to the outer surface of the extender element.

Optionally, the vehicle element may comprise at least one of (i) a vehicle emblem, (ii) a vehicle decal, (iii) a vehicle indicia, (iv) an exterior trim element of the vehicle, (v) a rear tail gate handle or latch portion, (vi) a deck lid handle or latch portion, and (vii) a light bar element of the vehicle. Optionally, the vehicle element may comprise a vehicle emblem, and the extender element may be shaped to substantially match a shape of the vehicle emblem so that the vehicle emblem substantially encompasses the outer surface of the extender element.

Optionally, the imaging device may comprise a pixelated imaging array having a plurality of light sensing photosensor pixels or elements, such as a two dimensional array of light sensing photosensor elements arranged on a semiconductor substrate. The imaging device may comprise a monochromatic imaging device or a black and white imaging device or a color imaging device. Optionally, the imaging device may comprise a CMOS imaging device and/or a color CMOS imaging device.

Therefore, the present invention provides an imaging device for a vehicle that may be positionable at a generally central location of a rear portion of a vehicle, and that may provide a generally downward and rearward field of view at the rear of the vehicle. The imaging device is proud of or positioned outward from a rear portion of the vehicle so that the downward field of view encompasses a portion of the rear of the vehicle, such as a vehicle bumper or the like. The imaging device may be fixedly positioned at the body surface or rear of the vehicle and thus the imaging system does not include costly and complex mechanical devices for extending and retracting the imaging device. The imaging device is positioned within an extender element that is substantially hidden or not readily noticeable or discernible by a person viewing the rear of the vehicle, so that the present invention provides a substantially concealed imaging device at a central region of the rear of the vehicle. A vehicle element, such as a functional element or a styling element, such as an exterior trim element or emblem or the like, is disposed at or attached to an outer surface of the extender element to substantially conceal or render covert the extender element and imaging device.

These and other objects, advantages, purposes and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings and the illustrative embodiments depicted therein, an imaging device or imaging sensor or camera 10 is located at a rear portion 12 a of a vehicle 12 and has a generally rearward and downward field of view (FIGS. 1-5). As shown in FIGS. 1-5, imaging device 10 is located within a housing or encasement or extender element or tube 14 that protrudes rearwardly from the rear portion of the vehicle and that has a vehicle element 16 thereon, such as a vehicle emblem or decal or indicia or the like, so that the imaging device is not readily noticeable or discernible at the rear of the vehicle. The imaging device 10 thus is disposed at a location that is proud of or rearward of the rear surface of the rear portion 12 a (such as a tailgate or lift gate or deck lid or the like) of the vehicle 12, such that the imaging device 10 may be directed substantially downward to have a field of view that encompasses the area immediately rearward of the vehicle and that includes a rear portion of the vehicle, such as a rear bumper 12 b of the vehicle.

Typically, a vehicle will have a decal or emblem or indicia or label at the rear of the vehicle (such as a decal identifying the manufacturer or line or type of the vehicle). The vehicle element or decal 16 is typically attached or adhered to the rear of the vehicle (such as, for example, to a sill or trim portion 18 at the rear portion of the vehicle and establishing an overhang at the license plate recess or well 12 c). The vehicle element 16 may be adhered to the rear trim portion 18 via a double-sided tape, or other means for adhering or attaching the decal may be implemented depending on the particular application. The vehicle element 16 thus may be removably attached to the rear of the vehicle, and may be removed therefrom, such as by a mechanic or a technician.

As best shown in FIGS. 3-5, imaging device 10 may be located within extender element or tube 14, which may be a generally cylindrical, hollow casing that may extend generally rearwardly from the rear trim portion 18 or from the rear panel of the vehicle. In the illustrated embodiment, the extender element 14 is generally cylindrical to generally match or correspond to the shape of the vehicle element 16 of the vehicle. However, the extender element may comprise any other shape depending on the shape of the vehicle element or decal or indicia or the like of the particular application of the imaging device and imaging system. For example, the extender element may be generally rectangular-shaped for applications on a Volvo vehicle, where the indicia is “VOLVO” at the rear, generally central region of the deck lid.

Thus, the vehicle element or emblem or decal 16 of a vehicle 12 may be removed, and the extender element 14, with imaging device 10 positioned therein, may be attached, such as via adhesive or welding or the like, to the rear portion 12 a or rear surface or trim portion 18 of the vehicle. Optionally, a recess or aperture may be formed in the rear portion or trim portion for receiving the extender element at least partially therein to attach the extender element to the vehicle. When so attached, the extender element 14 protrudes rearwardly from the rear portion 12 a of the vehicle so that the imaging device may be positioned rearward of the rear surface of the rear portion of the vehicle with a generally downward field of view. The emblem or decal or vehicle element 16 may be attached or adhered to the outer surface or outer end 14 a of the extender element 14, so that the extender element is partially hidden by the emblem or decal or vehicle element, and the extender element and imaging device are thus not readily noticeable or discernible at the rear of the vehicle. For example, the original emblem or decal or the like may be reattached to the extender element or a new emblem or decal or the like may be attached to the extender element and thus may replace the original emblem or decal or the like.

The extender element 14 may comprise any suitable material, such as a metallic material or a polymeric material, and may be painted or colored to match the rear portion of the vehicle or the trim portion or the emblem or decal of the vehicle. Preferably, the outer side surface or surfaces and the rearward end surface of the extender element are finished to substantially match the surface finish of the rear portion of the vehicle or the trim portion (depending on where the imaging device and extender are attached and where the emblem or decal are attached to the vehicle), so that the extender element is not readily noticeable or discernible at the rear portion of the vehicle. Because the extender element 14 extends rearwardly from the rear portion of the vehicle, the extender element may be positioned at a generally central region of the rear portion of the vehicle, and will not interfere with a handle or latch or light or the like at the license plate well or recess at the rear of the vehicle.

The vehicle element may comprise any suitable element that provides camouflage at or renders covert the imaging device at the rear portion of the vehicle. For example, the vehicle element (that is attached to or adhered to or disposed at the outer portion of the extender element) may comprise a vehicle emblem or logo, a vehicle decal, a vehicle indicia, an exterior trim element of the vehicle, a rear tail gate handle or latch portion, a deck lid handle or latch portion, and/or a light bar element of the vehicle and/or the like. Optionally, for applications where the vehicle element comprises a vehicle emblem or logo or decal or the like, the extender element may be shaped to substantially match a shape of the vehicle emblem or logo or decal so that the vehicle emblem or logo or decal substantially encompasses the outer surface of the extender element.

The imaging device may be secured within the extender element, with its lens positioned at or near a lower surface of the extender element (when the extender element is attached to the vehicle). A hole or passageway may be formed through the rear portion or panel and/or trim portion of the vehicle so that any wiring associated with the imaging device may be routed from the imaging device and extender element to the vehicle and to the control or image processor of the associated imaging system. The imaging device thus may be installed at the rear of the vehicle and may be wired or electrically connected to a control or processor of the vehicle, and may be installed and connected during manufacture of the vehicle or as an aftermarket device or system.

Optionally, and desirably, the imaging device may comprise a pixelated imaging array having a plurality of light sensing photosensor pixels or elements, such as a two dimensional array of light sensing photosensor elements arranged on a semiconductor substrate. The imaging device may comprise a monochromatic imaging device or a black and white imaging device or a color imaging device or the like. Optionally, the imaging device may comprise a CMOS imaging device and/or a color CMOS imaging device, such as by utilizing aspects of the vision systems and imaging devices described in U.S. Pat. Nos. 6,989,736; 6,757,109; 6,717,610; 6,396,397; 6,201,642; 6,353,392; 6,313,454; 6,396,397; 5,550,677; 5,670,935; 5,796,094; 5,877,897; 6,097,023 and 6,498,620, and U.S. patent application Ser. No. 09/441,341, filed Nov. 16, 1999, now U.S. Pat. No. 7,339,149; Ser. No. 10/427,051, filed Apr. 30, 2003, now U.S. Pat. No. 7,038,577; Ser. No. 10/534,632, filed May 11, 2005, now U.S. Pat. No. 7,965,336, and/or Ser. No. 11/315,675, filed Dec. 22, 2005, now U.S. Pat. No. 7,720,580, which are all hereby incorporated herein by reference in their entireties.

As shown in FIG. 6, the imaging device 10 may be associated with an imaging system 20 having a display device or element 22 at an interior portion of the vehicle for viewing by a driver of the vehicle. For example, and desirably, the display element may be located at an interior rearview mirror assembly 24. The imaging system 20 may process images captured by the imaging device 10 and may display the video images at the display device 22 at the mirror assembly 24 for viewing by the driver of the vehicle, such as display devices of the types described below. The image data may be communicated from the imaging device to the display device (or to an image processor or the like) via any suitable communication link or protocol. For example, the imaging device and the display device may communicate or output and receive signals utilizing aspects of the systems described in U.S. patent application Ser. No. 11/239,980, filed Sep. 30, 2005, now U.S. Pat. No. 7,881,496, and/or U.S. provisional applications, Ser. No. 60/628,709, filed Nov. 17, 2004; Ser. No. 60/614,644, filed Sep. 30, 2004; Ser. No. 60/618,686, filed Oct. 14, 2004, which are all hereby incorporated herein by reference in their entireties.

The imaging device thus may be located at a generally central region of the vehicle and may be positioned so as to have a generally or substantially downward field of view so as to capture images of the area immediately rearward of the vehicle. The field of view of the imaging device may include a rear portion of the vehicle, such as a rear bumper of the vehicle or the like, so as to provide a reference for the driver when viewing the video images within the vehicle, such as during reverse maneuvering of the vehicle. The imaging device thus may be covertly disposed at the rear of the vehicle so as to be substantially camouflaged or rendered covert, while protruding a sufficient amount rearward of the rear surface of the rear of the vehicle so as to provide a generally downward and rearward field of view for capturing images of the area substantially immediately rearward of the vehicle, such as for a backup assist system and display. The imaging device and/or a lens or housing or other elements associated with the imaging device may utilize aspects of the imaging devices described in U.S. Pat. Nos. 6,989,736; 6,757,109; 6,717,610; 6,396,397; 6,201,642; 6,353,392; 6,313,454; 6,396,397; 5,550,677; 5,670,935; 5,796,094; 5,877,897; 6,097,023 and 6,498,620, and U.S. patent application Ser.

No. 7,965,336, and/or PCT Application No. PCT/US2006/041709, filed Oct. 27, 2006, published on Dec. 31, 2008, as International Publication No. WO 2007/053404, which are all hereby incorporated herein by reference in their entireties.

Optionally, the imaging device and/or the display device may be activated to capture and display images of the rearward and downward field of view in response to the vehicle being shifted into a reverse gear. Thus, the display may be episodically actuated only when it is desired or appropriate to display the area immediately rearward of the vehicle, such as when the driver is performing rearward driving maneuvers, and may be deactivated when it is no longer suitable for displaying the rearward images, such as when the driver shifts the vehicle into a forward gear for forward driving.

The display or display device preferably comprises a video display device for displaying video images of the scene substantially immediately rearward of the vehicle. For example, the video display device of the imaging system may comprise an LCD type back lit video display, such as the types described in U.S. Pat. No. 6,847,487; PCT Application No. PCT/US03/40611, filed Dec. 19, 2003, published on Jul. 15, 2004, as International Publication No. WO 04/058540; PCT Application No. PCT/US2006/042718, filed Oct. 31, 2006, published on Apr. 23, 2009, as International Publication No. WO 2007/053710; U.S. patent application Ser.
